A kind of method of loach parental anesthesia

Abstract

The invention discloses a method for efficiently anesthetizing a loach parent. The method includes the steps that A, a selected loach parent is fished out, and is placed in a prepared plastic basin after being drained off; B, anesthetic is dissolved in clear water, and is poured into the plastic basin after being dissolved; C, the loach parent reacts fiercely, the upper portion of the plastic basin is covered with another plastic basin so as to prevent the loach parent from jumping out, and anesthesia is completed after 3-5 minutes; D, oxytocic begins to be injected, the loach parent is placed in clear water after injection is completed, and after reviving completely in 5-10 minutes, the loach parent is placed in spawning equipment for awaiting delivery; tricaine methanesulfonate is selected to serve as the anesthetic; the using dosage of the anesthetic is 10 mg / kg, and the anesthetic is dissolved in 10-30 ml of clear water in the using process. The method is easy to implement and simple and convenient to operate, the fast anesthetic effect is achieved through the skin permeation action, and therefore the spawning induction efficiency of loaches is improved obviously.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for efficient anesthesia of loach parents, which can also be used for anesthesia of other types of loach and paraloach. technical background [0002] Loach is one of the emerging breeding species in my country in recent years. The market demand is increasing year by year, and the breeding boom is very high. Loach is a small freshwater economic fish, which is mainly distributed in East Asia. It has high nutritional value and is known as water ginseng. . However, the seed of loach breeding industry in my country mainly comes from wild seed, which is mainly due to the high mortality rate in the process of large-scale cultivation of loach seed, while wild seed has the problems of being difficult to domesticate artificial feed and unstable survival rate. Therefore, the cultivation of artificial seedlings is crucial to the healthy development of the loach industry. The artificial r...

Problems solved by technology

However, the traditional anesthesia method with water is not ideal for loach. Practice shows that it is difficult for loach to achieve anesthesia effect under the condition of water anesthesia. The main reason should be that loach has intestinal respiratory function. It is difficult to enter the body of loach through the gills. To achieve anesthesia effect through skin penetration, a very high concentration of anesthetic is required. The cost of anesthesia with water is too high for loach, so it is not suitable to use

Thereby publication number is that the loach oxytocin and hatching method that the patent of CN 104082200 A and CN 104094878 A provide does not adopt anesthesia method, has used the method of artificial fixation
